Penn-Plax Standard Airline Tubing for Aquariums – Clear and Flexible – Resists Kinking – Safe for Freshwater and Saltwater Fish Tanks – 500 Feet

As aquarists and fish-keeping hobbyists know, it’s always good to have extra airline tubing on hand. Our Standard 3/16” Airline Tubing offers a great solution for various aquarium airline needs, such as connecting an air pump to an air stone, an under-gravel filter, or an aquarium ornament. Clear, Flexible, and Durable: Made from clear, flexible plastic, our Standard 3/16” Airline Tubing is built to withstand wear and tear. The tubing’s flexibility makes it a breeze to work with. In addition to being resistant to kinking, it’s ultra-durable and should not crack or become brittle. Our tubing fits seamlessly in any home aquarium, and virtually disappears in the water! For better connection to aquarium accessories, soak both ends in warm water for 30 seconds. This will allow the ends to stretch more when connecting with a tight fit. Safe for Fish: Our Standard 3/16” Airline Tubing is made of fish-safe plastic, and can be used for both freshwater and saltwater tanks.
